The diagnosis kit for Mycobacterium species identification and drug-resistance detection in accordance with the present invention consists of an oligonucleotide chip including a Mycobacterium tuberculosis complex probe, a Mycobacterium species identification probe and a drug-resistance detection probe of a  Mycobacterium tuberculosis  rpoB gene, and a fluorescent material containing a biotin-binding protein so as to detect hybridization of amplified products of a specimen marked as biotine and the corresponding probe.

TECHNICAL FIELD

[0001] The present invention relates to a diagnosis kit for Mycobacterium species identification and drug-resistance detection and a manufacturing method thereof, and more specifically, to a diagnosis kit for Mycobacterium species identification and drug-resistance detection in which point mutations of Mycobacterial rpoB gene related to the drug-resistance can be discriminated speedily and accurately in large quantity by using an oligonucleotide chip, and a manufacturing method thereof.

BACKGROUND ART

[0002] About two million people die from tuberculosis worldwide each year. The increase in immigration, the spread of HIV/AIDS, and the emergence of drug-resistance strains are enhancing the mortality of tuberculosis. AIDS patients and newborns with weak immune system can develop tuberculosis from not only Mycobacterium tuberculosis infection but also MOTT (Mycobacterium other than tuberculosis) infection, particularly, Mycobacterium avium-intracellulare (MAI), Mycobacterium chelonae, Mycobacterium fortuitum, Mycobacterium kansasaii, Mycobacterium xenopi, Mycobacterium marinum, Mycobacterium scrofulaceum, and Mycobacterium szulgai.

[0003] Tuberculosis is normally treated by chemotherapy with various anti-tuberculosis drugs. Since there are numerous different strains of Mycobacteria with diverse drug-susceptibility, detection and identification of the causative bacterium is important for the effective treatment.

[0004] For the diagnosis of tuberculosis, chest X-ray examination and sputum test are commonly used. However, chest X-ray can often misdiagnose an already-cured inactive tuberculosis or other types of chest diseases as tuberculosis. Sputum test can be typically preformed by the following two methods: sputum smear microscopy in which sputum of a patient is thinly spread on a slide, and then the bacteria are selectively stained for microscopic observation, and culture method in which the bacteria are cultured under physiological conditions for visual observation. Sputum smear microscopy is relatively simple and rapid, but cannot easily discriminate Mycobacterium tuberculosis from MOTT. Detection and identification of the mycobacterium strains have been done by the culture method, but it takes at least 6-8 weeks due to the slow growth rate of the bacteria. During this period, a combination of primary anti-tuberculosis drugs is used, which may result in therapeutic failure and drug-resistance. In fact, increasing numbers of strains have been determined to be resistant to primary anti-tuberculosis drugs such as isoniazid (INH), rifampin (RIF), streptomycin (STR), ethambutol (EMB), pyrasinamide (PZA).

[0005] Therefore, in order to achieve effective control and treatment of tuberculosis, a necessity of rapidly identifying the causative bacterium at the initial stage of infection has been increasingly recognized. Recently, molecular biological techniques by which mycobacterial species identification can be made within a relatively short time have been devised. These methods use species-specific sequences of the mycobacterial genes such as IS6110 as the target DNA. However, the IS6110 gene has different copy numbers in various mycobacterial species and does not present in some species. Several reports indicate that the IS6110 gene is not mycobacterium-specific. Therefore, the use of IS6110 as target DNA may cause false-positive or false-negative results. The highly polymorphic region of 16S rRNA DNA has also been used for species identification since it shows species-specific polymorphism. Several commercial products have been developed based on this method: Accuprobe (Gen-probe, San Diego, Calif., U.S.A.) which can be applied directly to a specimen, and AMTD (Gen-probe, San Diego, Calif., U.S.A.) and Amplicor MTB (Roche Diagnostics Systems, Somerville, N.J., U.S.A.) in which target DNA are PCR (polymerase chain reaction) amplified prior to analysis to enhance sensitivity. However, the 16S rRNA gene occasionally has different copies in a single strain, and this could complicate accurate species determination. Moreover, in order to assess the drug-resistance, an additional molecular biological analysis on the rpoB gene has been necessary.

[0006] Hereinafter, point mutations of Mycobacterium tuberculosis related to drug-resistance are described in detail. Resistance against RIF, a primary anti-tuberculosis drug, is known to be related to the mutations of rpoB gene encoding RNA polymerase β-subunit. More than 30 different mutations identified so far have shown to be concentrated in the 81 bp core region of the 3,534 bp rpoB gene (Amalio Telenti, Paul Imboden, Francine Marchesi, Douglas Lowrie, Sterwart Cole, M. Joseph Colston, Lukas Matter, Kurt Schopfer, and Thomas Bodmer, “Detection of rifampin-resistance mutation in Mycobacterium tuberculosis” THE LACET, Vol.341, pp. 647-650, 1993).

[0007] Table 1 illustrates point mutations occurring in codons 507 through 533 of the M. tuberculosis rpoB gene. As illustrated in Table 1, point mutations occur more frequently in codons 513, 516, 526, and 531, which are also observed more prevalently than the others.

[0008] Rifabutin (abbreviated as RIB), a spiro-piperidyl derivative of rifamycin S, is used to prevent MAC infection in AIDS patients (James M. Musser, “Antimicrobial Agent Resistance in Mycobactera: Molecular Genetic Insights”, Clinical Microbiology Review, Vol. 8, No. 4, pp. 496-514, 1995). Resistance against RIB is also related to the point mutations of the rpoB gene. However, the drug-susceptibility of a mutation displays difference between RIF and RIB: Several mutations showing resistance to RIF have determined to be susceptible to RIB. Mutation showing resistance to both RIF and RIB were also reported (Della Bruna C., G. Schiopacassi, D. Ungheri, D. Jabes, E. Morvillo, and A. Sanfilippo, “A new spiro-piperidyl rifamycin: in vitro and in vivo studies”, J. Antibiot. Vol. 36, pp. 1502-1506, 1983, Dessen A., A. Quenmard, J. S. Blanchard, w. R. Jacobs, Jr., and J. C. Sacchettini, “Crystal structure and function of the isoniazid target of Mycobacterium tuberculosis” Science, Vol. 267, pp. 1638-1641, 1995). RIB has often been used to treat RIF-resistant infection, which were effective in many cases (Gillespie S. H., A. J. Baskerville, R. N. Davidson, D. Felmingham, and A. D. M. Bryceson, “The serum rifabutin concentrations in patient successfully treated for multi-resistant Mycobacterium tuberculosis infection”, J. Antimicrobi. Chemother. Vol. 33, pp. 661-674, 1990).

[0009] In addition, the species-specific characteristics of rpoB gene have been used for mycobacterial species identification. Korean Patent Registration No. 234975 discloses a method for the detection and identification of mycobacterial strains by PCR-RFLP (restriction fragment length polymorphism after polymerase chain reaction) assay using a set of novel PCR primers that specifically amplifies the rpoB gene of mycobacterial species. Also, Korean Patent Registration No. 285254 discloses a method of detecting and distinguishing Mycobacterium tuberculosis complex and MOTT by using primers that can amplify rpoB gene fragments of Mycobacterium tuberculosis complex and MOTT in a respectively different size.

[0010] However, the above-described methods require bacterial culture step prior to PCR amplification, limit the kind of species or the number of samples that can be analyzed, and are laborious having a PCR step followed by a restriction enzyme treatment step and/or an electrophoresis step.

[0011] In the Korean Patent Registration No. 285253, a method of detecting rifampin-resistance in Mycobacterium tuberculosis with a nested PCR-SSCP (polymerase chain reaction-single strand conformational polymorphism) and a single-step nested PCR-SSCP. This method include two PCR and polymorphism assay steps and therefore it takes about four days to determine rifampin-resistance.

[0012] PCT International Publication No. WO97/29212 by Affymetrix discloses a technology of a sequencing DNA chip of rpoB gene. With this method, the entire base sequences of 700 bp in the rpoB gene should be analyzes to obtain clinically important information such as species identity and drug-resistance.

DISCLOSURE OF THE INVENTION

[0013] To solve the above problems, it is an object of the present invention to provide a diagnosis kit for Mycobacterium species identification and drug-resistance detection in which features relating to both the Mycobacterium species identification and the drug-resistance detection can be discriminated speedily and accurately in large quantity.

[0014] It is another object of the present invention to provide a method of manufacturing a diagnosis kit for Mycobacterium species identification and drug-resistance detection in which features relating to both the Mycobacterium species identification and the drug-resistance detection can be discriminated speedily and accurately in large quantity.

[0015] It is still another object of the present invention to provide a set of primers of a polymerase chain reaction (PCR) for faster Mycobacterium species identification by enabling efficient PCR amplification of rpoB gene fragment (157 bp) of numerous species directly from uncultured specimens including sputum samples.

[0016] It is yet another object of the present invention to provide experimental conditions for polymerase chain reaction (PCR) for efficient amplification of the 157 bp fragment of rpoB gene from various Mycobacteria.

[0017] To accomplish the above objects of the present invention, there is provided a diagnosis kit for Mycobacterium species identification and drug-resistance detection comprising: an oligonucleotide chip including species identification probes comprised of species-specific DNA sequences of Mycobacterial rpoB gene, Mycobacterial drug-resistance detection probes comprised of one or more modified codons of Mycobacterial rpoB gene, and contrast group probes comprised of wild-type sequences corresponding to each drug-resistance detection probe; and a method for detecting the hybridization of the oligonucleotide chip and the specimen DNA.

[0018] By the above construction, drug-resistance detection as well as Mycobacterium species identification can be simultaneously performed. In particular, since Mycobacterial rpoB gene point mutations related to drug-resistance can be discriminated by comparing the intensity of hybridization signal of the drug-resistance detection probe with that of the contrast group probe, and species identification can be made by comparing the hybridization intensities of the species-specific probes, the Mycobacterial species identification and the drug-resistance detection can be performed speedily and accurately in large quantity.

[0019] According to a specific embodiment of the present invention, in said diagnosis kit for Mycobacterial species identification and drug-resistance detection, the drug-resistance detection probe comprises one or more modified codons discovered in 507-533 codons of rpoB gene.

[0020] By the above construction, since one or more modified codons discovered in 507-533 codons in which point mutations frequently occur are used as a probe, drug-resistance can be discriminated speedily and accurately with only part of the Mycobacterial rpoB gene.

[0021] According to a more specific embodiment of the present invention, in said diagnosis kit for Mycobacterial species identification and drug-resistance detection, the drug-resistance detection probes are rifampin-resistance probes and/or rifabutin-sensitive probes.

[0022] By the above construction, it can be discriminated speedily and accurately whether a specimen has rifampin-resistance and/or rifabutin susceptibility.

[0023] According to another embodiment of the present invention, there is provided a method of manufacturing a diagnosis kit for Mycobacterium species identification and drug-resistance detection comprising the steps of: (a) modifying species identification probes comprised of species-specific DNA sequences of Mycobacterial rpoB gene, Mycobacterial drug-resistance detection probes comprised of one or more modified codons of Mycobacterial rpoB gene, and contrast group probes comprised of wild-type sequences corresponding to each drug-resistance detection probe to contain an amine group on the 5′ terminal; (b) inducing an aldehyde group on glass; and (c) fabricating an oligonucleotide chip by immobilizing the modified probes on the glass by Schiff base reaction.

[0024] By the above construction, the diagnosis kit having the advantage of simultaneously discriminating Mycobacterium species identity and drug-resistance speedily and accurately in large quantity, can be easily fabricated.

[0025] According to another aspect of the present invention, a set of PCR primers for Mycobacterium species identification comprises DGR8 and DGR9 having base sequences by which Mycobacterial rpoB gene fragments (157 bp) are specifically amplified.

[0026] In the case that the primer set is used, DNA isolated from uncultured clinical specimens can be used as a template of a polymerase chain reaction, and the rpoB gene fragment (157 bp) of 44 species belonging to Mycobacterium genus can be efficiently amplified. Accordingly, the Mycobacterium species identification and the drug-resistance detection can be performed within a short time, for example, approximately in six hours. The PCR products obtained by using the primer set are DNA of 157 bp size that can be used as a target DNA of oligonucleotide chip analysis.

[0027] In a method for Mycobacterium species identification and drug-resistance detection according to still another aspect of the present invention, a fragment of rpoB gene in a specimen is PCR amplified under the reaction conditions such as an annealing temperature of 64° C., a reaction cycle of 40, and a primer concentration of 100 pmol with primers DGR8 and DGR9, and then the amplified product is used for Mycobacterial species identification and drug-resistance detection by using said diagnosis kit according to the present invention.

[0028] DNA chip technology developed in early 1980s presents a method of providing a large amount of genetic information at a time. This method has been used to investigate gene expression, mutation and polymorphism of human or bacterium genome.

[0029] The present invention utilizes the DNA chip technology that enables rapid genetic analysis, and provides a diagnosis kit for Mycobacterium species identification and drug-resistance detection and a manufacturing method thereof, in which the Mycobacterium species identification and the point mutations of Mycobacterium tuberculosis related to drug-resistance can be discriminated.

[0030] In the present invention, mutations occurring in the rpoB gene of Mycobacterium tuberculosis have been investigated to identify drug-resistant strains, based on the relationship between drug-susceptibility and rpoB gene mutation described in the background art. More specifically, the rpoB gene fragment (157 bp) including the 81 bp core region where Mycobacterial point mutations occur most frequently is PCR amplified using a particular primer set, and then the amplified DNA is hybridized with an oligonucleotide chip, to thereby detect point mutations for drug-resistance determination.

[0031] The method using said oligonucleotide chip includes a step of amplifying target DNA from clinical specimens by PCR. In order to successfully apply the method to clinical samples, PCR should be performed with highly efficient primers.

[0032] In Korean Patent Application No. 2000-0029369, biotin-TR8 and TR9 that have been devised by using only the rpoB gene base sequence of Mycobacterium tuberculosis are used as primers. The DNA amplified by using the primers is 157 bp fragment containing the 81 bp core region where point mutations related to rifampin-resistance occur most frequently. However, the amplification efficiency of biotin-TR8/TR9 primers is not sufficient for uncultured specimens such as sputum and therefore the analysis time with these primers exceeds 6-8 weeks due to bacterial culture step. MOTT may not be amplified even from cultured samples due to the low efficiency of these primers. In other words, a rapid analysis on the species identity and drug-resistance cannot be accomplished without DNA amplification directly from sputum samples.

[0033] Thus, the inventors combine base sequences of the rpoB gene of forty-three different species of Mycobacteria as well as Mycobacterium tuberculosis, to thereby devise a new primer set. When this primer set is used, isolated DNA from uncultured specimens can be used as a template for PCR, and a specific rpoB gene sequence of forty-three bacterial species as well as Mycobacterium tuberculosis can be amplified by a single PCR step. When the amplified product is applied to a DNA chip, the Mycobacterium species identification and rpoB mutation detection can be simultaneously performed within a short period of time.

[0051] According to the above order illustrated in Table 2, SEQ ID NOs 1-40 are assigned.

[0052] As illustrated in Table 2, an oligonucleotide chip for investigating point mutation of rpoB gene is devised including seven wild-type probes, seventeen RIF-resistance probes, and eight RIB-sensitive probes.

[0053] As a result, seventeen RIF-resistance probes of SEQ ID NOs 20-36 can discriminate the mutations of codon 511 (Leu>Pro), codon 513 (Gln>Pro), codon 516 (a: Asp>Val, b: Asp>Tyr, c: Asp>Glu), codon 518 (Asn>His), codon 521 (Leu>Met), codon 522 (Ser>Leu), codon 526 (a: His)Tyr, b: His)Asp, c: His)Arg, d: His)Asn, e: His)Ala, f: His>Cys, g: His)Gln, h: His>Gly), and codon 531 (Ser>Leu).

[0054] Eight RIB-sensitive probes of SEQ ID NOs 22, 23 and 31-36 among seventeen RIF-resistance probes can discriminate the mutations of codon 516 (a: Asp>Val, b: Asp>Tyr, c: Asp>Glu), and codon 526 (d: His>Asn, e: His>Ala, f: His>Cys, g: His>Gln, h: His>Gly).

[0055] Strains having mutation type 516a and 516b have shown conflict with respect to RIB-susceptibility as indicated in many reports (James M. Musser, “Antimicrobial Agent Resistance in Mycobacteria: Molecular Genetic Insights”, Clinical Microbiology Review, Vol.8, No. 4, pp. 496-514, 1995). The current format of the oligonucleotide chip includes 516a and 516b probes in RIB-sensitive probes.

[0056] Probes Mc1, Mc2, and Mc5 of SEQ ID NOs 1-3 devised in order to discriminate Mycobacterium species from other bacteria are mixed and affixed as a single spot on an oligonucleotide chip. From the positive reaction on the probes, Mc1 can detect M. tuberculosis, M. africanum, M. asiaticum, M. bovis (2), M. gastri, M. avium (2), M. celatium (2), M. genavense, M. gordonae, M. haemophilum, M. interjectum, M. intermedium, M. intracellulare, M. kansasii, M. leprae, M. malmoense, M. scrofulaceum, M. szulgai, M. xenopi, M. terrae, M. triviale, M. nonchromogenicum, M. aurum, M. chitae, M. peregrinum, M. phlei, M. smegmatis, M. thermoresistibile, and M. vaccae, Mc2 can detect pathogenic or non-pathogenic but clinically important M. marium, M. shimoidei, M. ulcerans, M. abscessus, and M. chelonae, and Mc5 can detect M. fortuitum. Also, probe Mex of SEQ ID NO 4 detecting Corynebacterium diphtheriae which is not mycobactria but belongs to similar but different genus as a contrast group, is added in order to compare hybridization signals with each other, to thereby enable a more accurate determination on whether or not the strain under examination belongs to Mycobacteria.

[0057] Eight Mycobacterial species identification probes of SEQ ID NO 5 through 12 including partial sequences of Mycobacterial species-specific rpoB gene have been added in order to perform Mycobacterial species identification in more detail, in addition to probes which can discriminate Mycobacteria from other similar bacteria. In the case of the Mycobacterium species identification probes, the Ms1 probe can detect M. tuberculosis, M. africanum, M. bovis, and M. gastri. The other probes have been devised to detect M. asiaticum (Ms2), M. simiae (Ms2), M. aurum (Ms2), M. senegalence (Ms2), M. shimoidei (Ms2), M. neoaurum (Ms2), M. terrae (Ms2), M. gordonae (Ms2), M. haemophilum (Ms2), M. szulgai (Ms2), M. intracellulare (Ms2), M. kansasii (Ms2), M. scrofulaceum (Ms2), M. fortuitum (Ms2), M. fallax (Ms2), M. flavescens (Ms2), M. peregrinum (Ms2), M. phlei (Ms2), M. vaccae (Ms2), M. marinumv (Ms2), M. ulcerans (Ms2), M. chitae (Ms2), M. genevense (Ms2), M. smegmatis (Ms2), M. intermedium (Ms3), M. malmonense (Ms3), M. nonchromogenicum (Ms3), M. leprae (Ms3), M. avium (Ms4), M. riviale (Ms4), M. celatium (Ms4), M. interjectum (Ms5), M. xenopi (Ms6), M. chelonae (Ms7), M. abscessus (Ms7), and M. hermoresistibile (Ms8) which are pathogenic or non-pathogenic but clinically significant and may need to be identified.

[0058] Additional species identification probes, MTAB and MF, have been devised to specifically detect M. tuberculosis (MTAB), M. africanum (MTAB), M. bovis (MTAB), M. bovis BCG (MTAB), M. intracelluare (MTAB), and M. kansasii (MTAB), M. fortuitum (MF), and M. flavescens (MF).

[0059] Embodiment 1-3: Fabrication of Oligonucleotide Chip

[0060]FIG. 1 is a flowchart view illustrating a process of fabricating an oligonucleotide chip for Mycobacterium DNA identification according to the present invention. As shown in FIG. 1, the oligonucleotide chip fabrication process includes: the first step (10) of modifying each of the Mycobacterium complex probes, Mycobacterium species identification probes having Mycobacterial species-specific DNA sequences of Mycobacterium rpoB gene, Mycobacterium drug-resistance detection probes including one or more modified codons of the Mycobacterium rpoB gene, and contrast group probes including wild-type sequences corresponding to each drug-resistance detection probes, to contain an amine group at the 5′ terminal; the second step (20) of introducing an aldehyde group on silylated slide glass; and the third step (30) of affixing the modified probe on the slide glass by Schiff base reaction, to thereby fabricate an oligonucleotide chip.

[0061] More specifically, a particular DNA probe (see Table 2) was dissolved in 3×SSC to a concentration of 200 pmol/μl. The DNA probe solution of 0.1-0.2μl was spotted on an aldehyde-derivatized slide glass (CEL Associates, Inc., MA, U.S.A), and reacted in a humidified incubator for 4 hours at 37° C. Then the slide glass was treated with 0.2% sodium dodecyl sulfate (SDS) solution for one minute, distilled water for one minute, and then with NaBH₄ solution (0.1 g NaBH₄, 30 ml PBS, and 10 ml EtOH) for five minutes. Finally, the slide glass was washed for one minute in distilled water and air-dried, and kept in a dark room at room temperature until it is used.

[0062] Embodiment 1-4: Polymerase Chain Reaction (PCR)

[0063] PCR has been performed in a total volume of 50 μl with 10 mM Tris-HCl (pH 8.3), 50 mM KCl, 1.5 mM MgCl₂, 1U Taq polymerase, 50 pmol biotin-TR8 and TR9 primers (see Table 2). Further, 1 mM dATP, dGTP, and dCTP of 2 μl each, dTTP of 1.5 μl, and 1 mM biotin-dUTP of 0.5 μl were added to randomly incorporate fluorescence labeling in the resulting target DNA. Table 3 illustrates the composition of PCR mixture. TABLE 3 PCR REACTION MICTURE COMPOSITION AMOUNT (μl) 10 × PCR buffer (MgCl₂-free) 5 MgCl₂ (25 mM) 3 dNTPs (1 mM each) 2 (dT 1.5) Biotin-dUTP (1 mM) 0.5 Primer 1: Bio-TR 8 (50 pmol/μl) 2 Primer 2: TR 9 (50 pmol/μl) 2 Tsq polymerase (5 unit/μl) 0.2 Template DNA 1

[0064] The PCR was performed for 35 cycles under the following conditions.

[0065] predenaturation: at 94° C., for 5 minutes

[0066] denaturation: at 94° C., for 30 seconds

[0067] primer annealing: at 63° C., for 30 seconds

[0068] polymerization: at 72° C., for 45 seconds

[0069] last extension: at 72° C., for 5 minutes

[0070] The PCR products produced through the above process are 157 bp including 81 bp core region, and has been identified by electrophoresis on a 2% agarose gel.

[0071] Embodiment 1-5: Hybridization and Scanning

[0072] A target DNA (157 bp) of 20 μl amplified by PCR was mixed with DNase buffer of 20 μl and DNase |(0.1 U/μl) of 1 μl, and treated at 0° C. for 5 minutes. The resulting target DNA was thermally treated at 99° C. for 10 minutes to inactivate the DNase |. The mixture was then treated with 3N NaOH of 4 μl at 25° C. for 5 minutes, and then treated at 0° C. for 5 minutes with Tris-HCl (pH 7.2) of 2 μl and 3N HCl of 4 μl. To the above mixture, 12×SSPE (saline-sodium phosphate-EDTA buffer) of 50 μl and 10% SDS of 0.5 μl were added, and then transferred on to an oligonucleotide chip for hybridization at 40° C. for 3 hours.

[0073] After hybridization, the oligonucleotide chip was washed with 2×SSPE and 0.03% SDS at 25° C. for 3 minutes, with 1×SSPE at 25° C. for 5 minutes, and then with 0.2×SSPE at 25° C. for 5 minutes to remove unreacted DNA. The oligonucleotide chip was dried at 25° C., and a mixture of 3×SSPE of 49 μl and streptavidin-R-phycoerythrin of 1 μl was added, then treated at 25° C. for 10 minutes. The stained oligonucleotide chip was washed twice with 1×SSPE for 1 minute, air-dried, and scanned with a laser fluorescence scanner (GMS 418 array scanner, TaKaRa, Japan).

[0074] The wild-type (wt) probes consist of seven 17 mer probes devised from rpoB gene sequence corresponding to codons 507-533, including the mutation site in middle (positions 8-12) and have maximum sequence overlaps between the wild-type probes. The present invention has been devised to accurately detect frequent point mutations by comparing the signal intensities of the rifampin-resistance probes with those of the corresponding wild-type probes, and simultaneously predict all point mutations found at 507-533 codons.

[0075] Each mutant probe is designed to have the most frequent mutation site located in the middle position (8-12 positions) of the probe as in the wild-type probes, to thereby enhance detection sensitivitiy and enable more accurate detection by comparing the signal intensities with wild-type probes. The hybridization efficiency was increased by attaching a T₁₀ spacer on each probe, which is confirmed experimentally. It is considered that the T₁₀ spacer reduces steric hindrance and hence increases the hybridization efficiency of the target DNA and the probes.

[0076]FIG. 2 is a pictorial view showing the result in which rpoB gene fragments (157 bp) of ten clinical isolates are amplified using biotin-TR8 and TR9 primers and then undergone an electrophoresis in 2% agarose gel, according to the present invention. The ten amplified rpoB gene fragments (157 bp) were digested with DNase I, and then hybridized with the oligonucleotide chip. After hybridization under the optimal conditions, that is, at 40° C. for 3 hours, the oligonucleotide chip was stained with streptavidin-R-phycoerythrin for subsequent fluorescence scanning at 578 nm. The resulting image can be analyzed for drug-resistance by comparing the fluorescent intensities of the wild-type (wt) probes with those of the mutation (mt) probes relatively. Mutant probes and wild-type probes have identical sequence except for a few base difference in the middle of the sequence. The target DNA of a mutant will show stronger signal on the corresponding mutant probe than its wild-type probe. The difference in hybridization intensity is visually recognized for determination. The signal intensity can also be arithmetically valued for more accurate comparison by using an appropriate software.

[0077]FIGS. 3A through 3J are pictorial views showing fluorescent images obtained by amplified clinical samples containing biotin-dUTP using an oligonucleotide chip, according to the present invention. FIG. 4 is a view showing the positions of the probes in the FIGS. 3A through 3J views, in which each probe is established into separate blocks to facilitate signal comparison and double spots are placed for each probe to increase analysis fidelity.

[0078] In FIG. 3A, the signals of the F1, F2, F4, F5, F6 and F7 which are the wild-type probes are stronger than those of the mutant probes, but the signal of the 516c mutant probe is stronger than those of the corresponding wild-type probe F3 and the mutant probes 516a and 516b. Therefore, the specimen was determined as a 516c mutant. In FIGS. 3B through 3J, the specimens were identified in the same manner as that of FIG. 3A.

[0079] As a result, as shown in FIGS. 3A through 3J, each clinical isolate was identified to contain the following RIF-resistance mutation(s): #22 (mt516c), #24 (mt516b/526e), #30 (mt531), #36 (mt516b), #48 (mt526f), #82 (mt531/516c), #87 (mt531/516c), #90 (mt516c/526d), #91 (mt531), and #94 (mt511/531).

[0080] Also, the clinical isolate revealing RIB-susceptibility among them were #22 (mt516c), #24 (mt526b/526e), #36 (mt516b), #48 (mt526f), #82 (mt531/516c), #87 (mt531/516c), and #90 (mt516c/526d). When the above result was compared with that of drug-susceptibility test result or DNA sequencing, a discrepancy was found at #24. It showed RIB-resistance in drug-susceptibility test but was determined as RIB-sensitive 526e mutant by sequencing. The oligonucleotide chip result showed signals on both RIB-resistant mt 526b and RIB-sensitive mt 526e. Based on these results, the sample is considered to contain two types of mutations or two different strains producing mixed results.

[0081] L. B. Heifets has reported that strains having mutations of 511 (Leu>Pro), 516 (Asp>Tyr), 516 (Asp>Val), and 522 (Ser>Leu) are classified as low-level resistance strains with rifabutin MIC≦5 μg/ml (Heifets L. B., Antituberculosis drugs: antimicrobial activity in vitro, pp. 14-57 in L. B. Heifets (ed.), Drug susceptibility in the chemotherapy of mycobacterial infections, 1^(st) ed. CRC Press, Boca Raton, Fla., 1991). For these cases, the drug-susceptibility test is necessary in addition to the oligonucleotide chip experiment.

[0082] In the cases of codon 526 mutants, it has been clearly determined that His>Gln, Gly, Asn, Ala, or Cys, are RIB-susceptibility whereas His>Tyr, Pro, Arg, or Asp are RIB-resistance, therefore, oligonucleotide chip experiment alone can discriminate RIB-susceptibility.

[0083]FIG. 5 is a diagram showing an array format of the oligonucleotide chip using probes Ms1-Ms8 designed for species identification. FIGS. 6A through 6C are pictorial views showing the experimental results of Mycobacterium species identification using the oligonucleotide chip of FIG. 5. In the case of Mycobacterium kansasii, Mycobacterium fortuitum, and Mycobacterium scrofulaseum, the signal of MCmix probe indicating mycobacteria appears more strongly than that of the control Mex probe, and the signal of number 2 probe is stronger than those of numbers 1, and 3-8 probes, among the species identification probes. Likewise, clinically significant 33 kinds of Mycobacteria can be identified. In the case of Mycobaterium tuberculosis, the signals of the Mcmix probe and number 1 probe turn on, MOTT except for Mycobacterium gastri can be confirmed by signals on the Mcmix probe and the number 2 through number 8 probes.

[0084] In the following embodiment 2, the materials used were: sixteen different species of Mycobacterial genomic DNA have been provided from the Jeju University (Jeju, Korea). DNA probes and primers were custom-synthesized from Bionics (Seoul, Korea). All other reagents were first-grade.

[0085] Embodiment 2-1: Fabrication of Oligonucleotide Probe

[0086] Additional probes detecting mutations of the rpoB gene of rifampin-resistance Mycobacterium tuberculosis can be used with above-mentioned drug-resistance probes. Base sequences of three additional probes and their corresponding wild-type probes are shown in Table 4. TABLE 4 PROBE BASE SEQUENCE DRUG-SUSCEPTIBILITY IDENTIFICATION Mt509 5′amine-t10-ggcaccagacagctgag-3′ RFP-R, RBU-S 509 MUTANT Mt533 5′amine-t10-tgtcggcgccggggccc-3′ RFP-R, RBU-R 533 MUTANT Mt524 5′amine-t10-tgtcggggttaacccac-3′ RFP-R, RBU-R 524 MUTANT Wt509 5′amine-t10-ggcaccagccagctgag-3′ RFP-S, RBU-S 509 WILD TYPE Wt533 5′amine-t10-tgtcggcgctggggccc-3′ RFP-S, RBU-S 533 WILD TYPE Wt524 5′amine-t10-tgtcggggttgacccac-3′ RFP-S, RBU-S 524 WILD TYPE

[0087] By comparing fluorescent intensities of probes, mutations such as codon 509(Ser)→AGA(Arg), codon 533 CTG(Leu)→CCG(Pro), codon 524 TTG(Leu)→TTA(Leu) can be detected. In Table 4, RFP represents rifampin, RBU represents rifabutin, R represents resistance, and S represents susceptibility.

[0088]FIG. 7 is a diagram showing the array format of an oligonucleotide chip containing additional RIF-resistant probes. FIGS. 8A through 8D are pictorial views showing the diagnostic result regarding rifampin-resistance and rifabutin-sensitivity of clinical isolates using the oligonucleotide chip of FIG. 7. The clinical isolates used in the experiment were supplied from the Asan Medical Center (Seoul, Korea). Mutations in the samples were identified in the same manner as that of the embodiment 1 as #1 (516a mutant), #2 (511 mutant), #3 (516b mutant), and #4 (531 mutant), as shown in FIGS. 8A-8D. All the samples were Mycobacteria strains as judged by comparing Mcmix probe with Mex probe. The result of DNA sequencing agreed with the oligonucleotide chip results in all cases.

[0089] Embodiment 2-2: Fabrication of Primer

[0090] The inventors used biotin-TR8 and TR9 primer set in the prior application, but has devised a new primer set, biotin-DGR8, DGR9, that can amplify Mycobacterium tuberculosis and MOTT from uncultured specimens such as sputum, with an increased efficiency compared to biotin-TR8/TR9.

[0091] The new primer set, biotin-DGR8, DGR9, has been devised by mixing partial base sequences of rpoB genes of forty-three kinds, that is, M. africanum, M. asiaticum, M. avium, M. bovis, M. bovis BCG strain French 1173P2, M. celatum strain ATCC51131, M. celatum strain ATCC51130, M. gastri, M. genavense, M. gordonae, M haemophilum, M. interjectum, M. intermedium, M. intracellulare, M. kansasii, M. leprae, M. malmoense, M. marinum, M. avium subsp.

[0100] Embodiment 2-3: Polymerase Chain Reaction (PCR)

[0101] In order to find optimal conditions for PCR using the newly devised biotin-DGR8 and DGR9 primer set, reaction conditions were varied as follows:

[0102] A. Temperature Program

[0103] a. at 94° C. for 5 minutes, at 94° C. for 30 seconds, at 47° C. for 30 seconds, and at 72° C. for 45 seconds

[0104] b. at 94° C. for 5 minutes, at 94° C. for 30 seconds, at 63° C. for 30 seconds, and at 72° C. for 45 seconds

[0105] c. at 94° C. for 5 minutes, at 94° C. for 30 seconds, at 64° C. for 30 seconds, and at 72° C. for 45 seconds

[0106] d. at 94° C. for 5 minutes, at 94° C. for 30 seconds, at 65° C. for 30 seconds, and at 72° C. for 45 seconds

[0107] The yield of PCR product using the biotin-DGR8 and biotin-DGR9 primers changed depending on the annealing temperature, as dertermined by a 2% agarose gel electrophoresis. At the annealing temperature of 64 or 65° C., maximum yield was obtained with less amount of side products of different size that appeared at 47 or 63° C.

[0108] B. Reaction Cycle

[0109] Using the biotin-DGR8 and biotin-DGR9 primers, the amplified products of the polymerase chain reaction performed at 64° C. annealing temperature showed a single band with 35 cycles or 40 cycles as identified by a 2% agarose gel. The quantity of the amplified products was observed to be dependent on the reaction cycle, producing higher yield at 40 cycles. The most optimal PCR conditions were 64° C. and 40 cycles.

[0110] C. Primer Concentration

[0111] Using various concentrations of biotin-DGR8 and DGR9 primers, 50 pmol, 100 pmol, 500 pmol, and 1000 pmol, the polymerase chain reaction was performed at an annealing temperature of 64° C. for 40 cycles. It was observed that the yield increased within 50˜100pmol concentration range but decreased with over 100 pmol. Therefore, biotin-DGR8 and DGR9 primer concentrations of 50-100 pmol are considered appropriate.

[0112] Using the optimal conditions determined experimentally as described above, sixteen different Mycobacterial species were PCR amplified. FIG. 9A is a pictorial view showing a 2% agarose gel image of PCR amplified products under the reaction conditions disclosed in the prior application of the inventors, that is, at 63° C. and 35 cycles with biotin-TR8 and TR9 primers of 50 pmol, and FIG. 9B is a pictorial view showing a 2% agarose gel image of PCR amplified products under the reaction conditions according to the present invention that is, at 64° C. and 40 cycles with biotin-DGR8 and biotin-DGR9 primers of 100 pmol.

[0113] As illustrated in FIGS. 9A and 9B, the primer set of the present invention, biotin-DGR8 and DGR9, showed more efficient amplification of the rpoB 157 bp region in all sixteen Mycobacterial species compared to biotin-TR8 and TR9 primers. The 157 bp amplified products can be used as the target DNA for oligonucleotide chip analysis.

[0114] Embodiment 2-4: Drug-Resistance Diagnosis of Sputum Specimen

[0115] Eleven DNA samples directly extracted from sputum specimens of tuberculosis patients or suspected patients were obtained from the Department of Respiratory Diseases, Asan Medical Center (Seoul, Korea).

[0116]FIG. 10 is a pictorial view showing a 2% agarose gel image of PCR amplified products of sputum specimens under conditions as optimized in the embodiment 2-3 according to the present invention, i.e. 64° C. and 40 cycles with biotin-DGR8 and DGR9 primers of 100 pmol. As shown in FIG. 10, Mycobacterium tuberculosis was not detected from #16 and #36 specimens. Nine specimens except for the above #16 and #36 specimens were determined as Mycobacterium tuberculosis positive. Thus, diagnosis by oligonucleotide chip to detect drug-resistance was performed using the oligonucleotide chip of FIG. 7. As a result, it was determined that eight specimens including #6, #20, #26, #27, #29, #38, #41, #49 were wild-type, that is, rifampin sensitive strains, and #57 was a resistant strain having mutations on codons 509 and 513. FIGS. 11A through 11B show the images obtained from oligonucleotide chip experiments: #27 (wild-type) #57 (509, 513 mutant), respectively. DNA sequencing result of the eight wild-type strains agreed with the oligonucleotide chip result and #57 was determined to be a rifampin-resistance strain by drug-susceptibility test.

[0117] Embodiment 2-5: Random Labeling Incorporating Cyanine 5-dUTP

[0118] A new detection method has been devised to reduce assay time compared to the prior application method that uses streptavidin-R-phycoerythrin staining after PCR incorporating random biotin labeling. More specifically, PCR was performed with Cyanine 5-dUTP (NEN, U.S.A) instead of biotin-dUTP to incorporate Cyanine randomly to the amplified products, which does not require a separate staining procedure prior to scanning. Accordingly, an obvious visual result can be obtained speedily and simply. At the time of a polymerase chain reaction, a concentration of Cyanine 5-dUTP used equals to that of biotin-dUTP of the existing method, and it is preferable that DGR8 without biotin modification is used as a primer. The experimental conditions are the same as the existing method except that the staining process is omitted and that 633 nm is used in fluorescence scanning

[0119] The pars which are not particularly described in the embodiments 2-1 through 2-5 are same as those of the embodiments 1-1 through 1-5, which will thus be omitted.

[0120] Industrial Applicability

[0121] Finally, as described above, the present invention can perform Mycobacterial species identification and drug-resistance detection with only a portion of Mycobacterial rpoB gene (157 bp), simultaneously, speedily and accurately in large quantity, which can provide useful information in tuberculosis treatment so that an appropriate drug remedy can be given to the patients. Thus, at an early stage of the Mycobacterium infection, a proper administration of antibiotic agents and other necessary treatment can be provided to patients infected with mycobacteria.
